As said before, the main two are waninkoko's dvd dumper and superdump. personally, I prefer superdump. It s much faster (30 mins to dump a SL disc). I never could dump a game using dvd dumper in less than 5 hours . It s strongly recommended to use a cIOS rev 13 or less or 15, but NOT rev 14.

You would put all the bin files in a folder (directory), navigate to that location using the cmd prompt (or use
CmdHerePowertoySetup.exe which adds "Open Command Window Here" to XP's file list) and then run the command "copy /b 0.bin+1.bin wii.iso" which would copy the files "0.bin" and "1.bin" to a new file "wii.iso".

If your not at all familiar with navigating using cmd the easiest thing is to use the nice GUI app ncConcat made by nubecoder.

From the cmd window (cd = Change Directory)

cd \Documents and Settings\[Your User Name]\Desktop
cd MyBins (change to the temp directory "MyBins" that's on the Desktop.)
dir (list the files in "MyBins" to make sure we're in the right place.)
copy /b 0.bin+1.bin wii.iso (create a new file "wii.iso" in the directory "MyBins")

That's it done. If you needed to change the drive you were navigaiting the command would be "C:" for the C drive, "D:" for the D drive, etc.

No problem, just the locations of the directories change ie. \Users\[Your User Name]\Desktop

type "cmd" in the search bar to open a command window. It should already show your in your user name directory ie. "C:\Users\[Your User Name]>"

then

cd Desktop\MyBins (change to the temp directory "MyBins" where your've stored the bin files and that's on the Desktop.)
dir (list the files in "MyBins" to make sure we're in the right place.)
copy /b 0.bin+1.bin wii.iso (create a new file "wii.iso" in the directory "MyBins")

That's it done.
(ps. I don't know how many bin files it is in reality so it could be 0.bin+1.bin+2.bin+3.bin+... etc.)

C:\Users\Alan>cd DesktopC:\Users\Alan\desktop>copy /b 0.bin+1.bin+2.bin wii.iso
Wait for the new file to be created, and close the cmd window
You have now on your desktop the new and complete wii.iso file, and still 0.bin, 1.bin, 2.bin
